## About me

I am a research engineer at Meta AI, FAIR labs. Previously, I was a senior research scientist at Babylon Health, UK. Before that, I was a research associate, working with Zoubin Ghahramani at the Machine Learning group, CBL, University of Cambridge and member of Trinity Hall college.
I studied my PhD at the Gatsby Unit, UCL, my supervisor was Yee Whye Teh.
